HAZARDS IDENTIFICATION EMERGENCY OVERVIEW: White free-flowing, odorless powder. Powder becomes slippery when wet. Accumulation of overhead settled dust may form explosive concentrations in air when disturbed and dispersed. POTENTIAL HEALTH EFFECTS: No significant health hazard expected. Page 1 of 9

3. COMPOSITION / INFORMATION ON INGREDIENTS Chemical Name CAS# Wt.% EC No. EC Class Microcrystalline cellulose 9004-34-6 232-674-9 Not Classified 4. FIRST AID MEASURES EYES: Flush with plenty of water. Get medical attention if irritation occurs and persists. SKIN: Wash with plenty of soap and water. INGESTION: Drink plenty of water. Never give anything by mouth to an unconscious person. If any discomfort persists, obtain medical attention. INHALATION: Remove to fresh air. If breathing difficulty or discomfort occurs and persists, obtain medical attention. NOTES TO MEDICAL DOCTOR: This product has low oral, dermal and inhalation toxicity. It is non-irritating to the eyes and skin, and non-sensitizing to the skin. Treatment is symptomatic and supportive. 5. FIRE FIGHTING MEASURES EXTINGUISHING MEDIA: Water FIRE / EXPLOSION HAZARDS: The accumulation of excessive dust on overhead structures may produce explosive concentrations when disturbed and dispersed. According to NFPA 68, (Explosion Venting Guide), the Hazard Class of Dust Deflagrations for microcrystalline cellulose is St-1, the lowest hazard class. FIRE FIGHTING PROCEDURES: For fires involving this material, do not enter any enclosed or confined fire space without wearing full protective clothing and self-contained breathing apparatus (SCBA) approved for firefighting. This is necessary to protect against the hazards of heat, products of combustion and oxygen deficiency. Do not breathe smoke, gases or vapors generated. FLAMMABLE LIMITS: Page 2 of 9

6. ACCIDENTAL RELEASE MEASURES RELEASE NOTES: Powder becomes slippery when wet. Maintain good housekeeping practices to minimize accumulation of settled dust, especially on overhead surfaces. Sweep up the spilled material and dispose of in accordance with the waste disposal method outlined in Section 13, "Disposal Considerations". 7. HANDLING AND STORAGE HANDLING AND STORAGE: Use local exhaust or general dilution ventilation to control exposure to dust. Always use safe lifting techniques when manually moving containers, especially when shipping containers weighing more than 50 pounds (22.7 kg). To protect quality, store in a tight container in a dry place, at room temperature (approximately 25 C). Pallets should be stacked in a stable manner. Maintain adequate clearance from structural members and sprinklers; NFPA and U.S. OSHA state a minimum of 18 inches (45.7 cm) clearance shall be maintained between the top of storage and the ceiling sprinkler deflectors. 8. EXPOSURE CONTROLS / PERSONAL PROTECTION EXPOSURE LIMITS Chemical Name ACGIH OSHA Supplier Microcrystalline cellulose 10 mg/m 3 (TWA) 15 mg/m 3 (PEL) (total dust) 5 mg/m 3 (PEL) (respirable fraction of dust) PERSONAL PROTECTIVE EQUIPMENT EYES AND FACE: Whenever airborne dust concentrations are high, appropriate protective eyewear, such as mono-goggles, should be worn to prevent eye contact. RESPIRATORY: Whenever dust in the worker's breathing zone cannot be controlled with ventilation or other engineering means, workers should wear respirators or dust masks approved by NIOSH/MSHA, EU CEN or comparable certification organization to protect them against airborne dust. PROTECTIVE CLOTHING: No special clothing is required. GLOVES: No special gloves are required. COMMENTS: Page 3 of 9

TOXICOLOGICAL INFORMATION EYE EFFECTS: Non-irritating (rabbit) SKIN EFFECTS: Non-irritating (PII = 0/8.0) (rabbit) DERMAL LD 50 : > 2,000 mg/kg (rabbit) ORAL LD 50 : > 5,000 mg/kg (rat) INHALATION LC 50 : > 5.05 mg/l (4 h) (rat) Maximum attainable concentration - zero mortality SENSITIZATION: (Skin) Non-sensitizing (guinea pig) ACUTE EFFECTS FROM OVEREXPOSURE: This product has low oral, dermal and inhalation toxicity. It is non-irritating to the eyes and skin, and non-sensitizing to the skin. No significant acute toxicological effects are expected. CHRONIC EFFECTS FROM OVEREXPOSURE: Microcrystalline cellulose is considered an inert dust, which is not toxic to the lung when exposures are properly controlled. A 90-day animal study showed no adverse effects when administered in the diet. Microcrystalline cellulose was negative in the Ames mutagenicity assay, and caused no chromosome damage in the mouse micronucleus assay. No adverse human effects are known.
